Product Introduction
Infrared Methane Sensor is usedfor detecting methane content in the air of coal mines undergroundand it is flameproof and Intrinsic Safety type. The sensor is anintelligent detection instrument with infrared remote controlfunctions of zero setting, accuracy adjusting,and alarm pointsetting and with advantages of stable reliability and flexible use.The sensor has outputs of multiple standard systems, and can beused with all mine-used safety monitoring and control systems,locking devices of air-door, electricity and methane, and powerbreaking instruments for methane.
